我国微细气泡技术发展综述

Review of the Development of Fine Bubble Technology in China

微细气泡有很多优异性能,如比表面积大、停留时间长、界面ζ电位高、自身增压溶解、产生自由基、强化传质效率等,目前在国内外得到广泛应用.我国在胶片制作、医学、浮选、污水处理、采油及冶金工业等方面也有应用,特别是将微气泡用于强化钒渣氧化浸出,在常压反应条件下钒和铬的转化率可分别达90%和85%以上,并已成功用于万吨级全湿法钒渣清洁生产示范工程.与发达国家相比,我国的微细气泡技术缺乏系统性,微细气泡发生器的研发和生产仍是薄弱环节.建议有关组织建立相应的学/协会或工作委员会,以有效推动微细气泡技术在我国的研发和应用,助力中国制造业升级.对国际微细气泡技术及标准化工作也作了简单介绍.

A Fine bubble technology has been widely developed at home and abroad since fine bubbles have excellent properties, i.e. large specific surface area, stable, high ζ potential, free radical generation, intensifying transport efficiency, and etc. In China, it had been used in film industry, medical treatment, floatation column, waste water treatment, oil industry and metallurgical industry. But compared with developed countries, the fine bubble technology is not systematically developed in China and the research and manufacture of fine bubble generator are still the key shortness. It is reviewed that the development of fine bubble technology in China and suggested that some organizations be setup to promote its development. Also, a simple introduction of international fine bubble technology and their standardization was given.
